Denalis are famous for clogged fuel filters. Change the fuel filter first and see what happens, Get the code for the check engine light. It could be you have a clogged EGR ports. Remove EGR valve and clean out the ports, replace with new gasket and see what happens. Advise of results.

it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you

Remove bulb, make sure it sits tight in the socket. make sure socket is not burnt up (brown or black in color) Check bulb, if the filament inside is loose or discolored, replace as nesessary. Check brake light switch under driver side dash above brake pedal. make sure it is adjusted correctly.
